Ensign Aotorange 16-20 Repair
I have an old Ensign Autorange 16-20, Rangefinder Camera. There was a fair bit of dust in the lens and the slow shutter speeds are definitely slow. The main body of the lens dismantles happily but I have got to the stage when I think I need to remove the rangefinder arm and second lens from the front. There are no obvious screwheads on either the front or reverse. Does anybody have any experience with dismantling one of these cameras with the Epsilon shutter. I need to clean and lubricate the shutter mechanism. I have tried removing the second front lens using some bicycle inner tube glued onto the end of a fat dowel, but refuses to budge. If I cannot gain access to the mechanism I think it will be a job for a professional with a hefty bill at the end. Cheers .

You need to soak the threads at the base of the lens with a solvent, just a few drops, the thread grease sets like glue. I cleaned a lens similar to this on an old folder, because I was not too bothered if I messed it up I used a pair of gland pliers to free the front lens. The knack is to squeeze just enough to undo the lens not enough to break it. I cleaned all the gear trains with alcohol this dried them out and left them all too slow. So I tried watch oil, this leaked onto the shutter blades. Cleaned and tried watch oil again just the tiniest drop on the end of a paper clip. Left the shutter for a week, success the shutter and self timer work great! Them I taped a piece of grease proof paper on the back of the camera and looked through an slr to set the lens to infinity. Gogle setting a lens to infinity, you will find something. Good luck, please do not curse me if you attempt to remove the lens with gland pliers and you bust the glass, patience and soaking the threads is key!

I had a problem with an Ensign Autorange that you can read about below. It might be of some help to you.

GoodOldNorm and Brock
Thankyou for the information. I am a bit slow in responding as I had to put the camera back together quickly and pack stuff away because I had forgotten about a decorating promise. Now that is finished and out of the way I am free to tinker as much as I want. What solvent worked for you both ? I tried lighter petrol, but nothing budged. In my arsenal I have white spirit, methylated spirits, toluene and even a bit of xylene, dodgy stuff I know. I am a bit wary of stripping the paint and the mounting. Interesting article Brock. Am I correct in thinking that if I manage to unscrew the lens just in front of the diaphragm, the rangefinder arm and speed indicator dial will just lift off as one piece? No other screws etc. It is a bit of a puzzle to me, getting the arm off. Do I unscrew the lens in the centre using a rubber bung, or is the aluminium centre tube unscrewed. I think it should be the lens. Cheers and Thanks to you both.

Wd40, lighter fluid or PlusGas , warm the lens with a hair dryer put it onto some kitchen towel on a hot radiator and drip a a little solvent around the threads and leave it to soak . It may take several doses to soak the dry grease. Gripping the lens with a piece of sheet rubber or a rubber cup used for opening jam jars works for me, gland pliers are a last resort.
